A) blind spot.
B) visual cortex.
C) cornea.
D) lens.

The area where the optic nerve leaves the eye is called the blind spot because it does not contain any photoreceptor cells, resulting in a lack of vision in that area. The cornea is the clear outermost layer of the eye that helps to refract light onto the retina, while the lens is a transparent structure behind the iris that helps to fine-tune the focus of incoming light. The visual cortex is a part of the brain that processes visual information, but it is not located in the eye.
